Application feed january i7, 1914. serial No, 812.618.

To all w71 one it may] con/cm Be it known that l, LVAH C. ROEBUCK, a citizen ot' the United States, residing at lVoodstock, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Type-lVriters, ot' which the following is a specification.

This invention relates to Ytypewriters and more particularly to type bar pivots.

The principal object ofthe invention is to provide new and improved means for pivoting the type bars. A further object of the invention is to provide a construction of this kind in which the pivot wire may be taken out either from the rear or may be moved endwise in the pivot wire slot in either direction.

For the attainment otl these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the4 features of novelty in the construction, combination and arrangement of the several parts generally shown inthe accompanying drawing and described in the specification,

vr but more particularly pointed out in the appended claims.

In the drawings: Figure 1 is a front elevation of a type bar segment and pivot Wire construction embodying my invention; Fig, 2 is a rear elevation of the same; Fig. 3 is a sectional view taken on the line of Fig. 2, with a type bar shown in dotted outline; and Fig. l is a detailsectional view taken on the line 4.-4 of Fig. 2, -parts being broken away for clearness.

In pivoting the type bars of a typewriter machine, it is desirable that a simple, strong and etlicient construction be provided, with certain adjustability and with as few parts as possible to produce the :desired result.

This invention embodies aconstruc'tion in which the pivot wire is bodily removed rearwardly from the segment, or, by loosening the adjusting means, may be moved longitudinally in the groove in either direction.

In the present embodiment of my invention, a type har, segment 5 is provided with a reinforcement (3 about its curved edge, in which are a plurality of radial type bar slots '7. v

In one face ot the segment, preferably the rear face, is a groove 8 for seating the uni` versal bar not shown), and another groove 9 with an undercut portion 10 for receiving a pivot wire 11. This groove 2) extends parallel to the curved edge of the segment and to the extremities thereof, and is curved i about the same center as the curvature ot the outer edge of the segment,extending through the radial slots 7 of thesegment.

The pivot wire 11 is formed vat. one extremity with a blunt end 12 and at the otherv extremity4 with a wedging or beveled type 13. rThe pivot wire is adapted to be received in the undercut groove S) and is removable bodily from the groove or may-be moved longitudinally in the groove and removed from the segment in that manner.

Extending from the front face of the segment 5 and into the groove 9 are a pair of 70 screws, by means of which the pivot wire 11 is held lirmly, but adjustably, in position.v One ot' the screws, 14, is provided with an abutment portion 15, which is adapted to engage the blunt end of the pivot wire 11, and the other adjusting screw, 16, is prof vided with a conical or wedging extremity 17, `vhich is adapted to engage the Lbeveled extremity 13 of the pivot Wire. i

`When the type bars, one of which is shown in dotted outline 1S, are in positionin the slots 7 of the segment, the blunt extremity of the'pivot wire is moved against the abutment screw 14 at one end of the groove and the wedging screw 16 is forced againstA the 35v other extremity of the pivot wirethereby forcing the pivot wire firmly into the undercut portion Aof the groove and against the abutment screw 1l.

It' it. is desired to remove only the type 903 bars from one end of the segment, the adjusting screws 1l and 16 may be threaded out ot the groove 9, and the pivotwire moved longitudinally in the groove -in the other direction, thereby necessitating only the removal of a few of the type bars. If 'it is desired to remove all the type bars, the binding screws `are loosened and the entirepivot wire and the typebars may be bodily removed from the 'rear of the segment.

That I claim is: 1. The combination with a type'bar segment having an undercut groove therein, of a type bar pivot member, and means mov- `able at rightmngles to the member to con tact with the ends of the member to hold-it in the groove. E?. The' combination with a type bar segment having an undercut Agroove therein, of

a type bar pivot member, and wedging means movable at right angles to. the member for contacting with the ends of the meme -port1on ber to bind it '.releasably' inthe under groove. Y- 1f contact Witli-fthefends of the member and bindlthe member r vleasably in Ithe slot.

4.,-The combination with atype bar seg` groove in one face thereof, of a type' bar pivot member, andv means to forc the member into the undercut one face thereof curved yabout the same cenTl v`ter as the curvature Aof the segment and ex# ment havingv an undercut to bind itin the groove.
